2015 Acura RLX Interior

Its will be immediately found by the sheer amount of space in the 2015 Acura RLX. It feels noticeably more spacious than the old Acura RL or Acura TL. Legroom is abundant in the front and back, but 6-footers is the headroom in the back seat and clearance under the front chairs is closely low, so forget slide your feet under them. The front seats are wide and comfortable, but we found them lacking support on longer journeys. Trunk versatility is back seats that do not bend is limited, but its 15.3 cubic meters certainly is average for the segment. It does go up to 12 cubic feet with the sports hybrid, but that’s actually pretty good for a hybrid sedan.

With the navigation system is easy and intuitive as Acura, you can look up destinations from the central control dial, a new 7-inch touch screen interface or an advanced voice recognition system. Unfortunately, neither screen has the crisp graphics we come to expect in this class, and some of the basic functions require multiple relapses virtual touchscreen buttons that can be bothersome. A relatively small radio presets is another disappointment.
